Description

A kind of serial electric machine controller cooling structure
Technical field
The utility model belongs to new-energy automobile technical field.Be specifically related to a kind of can cooling electric capacity again can cooling IGBT new-energy automobile electric machine controller cooling structure.
Background technology
The application of new-energy automobile technology is conducive to solve environment and energy problem, and wherein electric automobile is the principal mode of new-energy automobile, and in electric automobile, Electric Machine Control one of is key technology.Thermal safety in Electric Machine Control, i.e. the too high meeting of working temperature declines to a great extent its performance and causes the safety problem of whole controller, is one of its difficult point.And the inner space of electric machine controller is narrow and small, the problems such as adopted fan cooling system, existence takes up room greatly, installation is complicated, it is inconvenient to safeguard, increase power consumption, therefore should not adopt which.
Current electric machine controller carries out cooling mainly for IGBT, the cooling problem of less consideration electric capacity, and under the bad condition of work condition environment, the heat that electric capacity produces also can reduce safety and the serviceability of electric machine controller.
Summary of the invention
The purpose of this utility model, be design a kind of do not take controller inner space, area of dissipation large, can be simultaneously to IGBT and electric capacity dispel the heat, radiating efficiency is high serial electric machine controller cooling structure.
Technical solution of the present utility model is: a kind of serial electric machine controller cooling structure, is characterized in that: comprise inlet channel, water outlet, U-shaped groove, connect water channel, IGBT cooling layer and motor controller casing; Wherein, described inlet channel, water outlet are positioned at a side of motor controller casing bottom; Described U-shaped groove is positioned at the motor controller casing bottom just right with electric capacity; Described IGBT cooling layer is positioned at the motor controller casing internal boss just right with IGBT; Inlet channel is connected with U-shaped groove one end, the U-shaped groove other end be connected water channel one end and connect, connect the water channel other end and be connected with IGBT cooling layer entrance point, the IGBT cooling layer port of export is connected with water outlet.Do not changing on the basis of controller internal structure, the position of inlet channel allows current directly flow to electric capacity cooling layer.
IGBT cooling layer described in technical solution of the present utility model adopts integral type flat structure, and its entrance point, port of export diagonal angle distribute, and the gamut that realizes IGBT is cooling, ensures IGBT cooling performance.
U-shaped groove described in technical solution of the present utility model is back-shaped water channel, ensures electric capacity cooling performance.
The utility model is owing to adopting by inlet channel, water outlet, U-shaped groove, connect water channel, the serial electric machine controller cooling structure that IGBT cooling layer forms, wherein, U-shaped groove is positioned at the motor controller casing bottom just right with electric capacity, IGBT cooling layer is positioned at the motor controller casing internal boss just right with IGBT, inlet channel is connected with U-shaped groove one end, the U-shaped groove other end be connected water channel one end connect, connecting the water channel other end is connected with IGBT cooling layer entrance point, the IGBT cooling layer port of export is connected with water outlet, thereby there is longer runner and larger area of dissipation, also increased the heat radiation time, make recirculated water first by the first cooling motor controller of U-shaped groove electric capacity, the working temperature of electric capacity is lower than IGBT, then enter IGBT cooling layer, improve system radiating efficiency.The utility model is owing to adopting the IGBT cooling layer of integral type flat structure and the design of diagonal angle, water channel gateway, thereby the cooling effect of the cooling guarantee of energy gamut IGBT, can in manufacture craft, reduce again volume, convenient installation.The utility model is owing to adopting the U-shaped groove of back-shaped water channel, thereby while making current flow through controller box, area of dissipation increases, and the Design of length of U-shaped groove is to calculate according to the area of dissipation of electric capacity, can be good at ensureing the cooling of electric capacity, and radiating effect is strengthened.The utlity model has the feature of saving electric machine controller inner space, reduction cooling system complexity, improving radiating efficiency.The utility model is mainly used in the cooling of new-energy automobile electric machine controller.
